A primal-dual fixed point algorithm for multi-block convex minimization
Peijun Chen, Jianguo Huang, Xiaoqun Zhang
We extend a primal-dual fixed point algorithm (PDFP) proposed in [5] to solve two kinds of separable multi-block minimization problems, arising in signal processing and imaging sci…

A primal-dual fixed-point algorithm for minimization of the sum of three convex separable functions
Peijun Chen, Jianguo Huang, Xiaoqun Zhang
Many problems arising in image processing and signal recovery with multi-regularization can be formulated as minimization of a sum of three convex separable functions. Typically, t…
